Our Approach
We combine data, technology, and proven media research methodologies to provide our members with a granular understanding of their OOH footprint.


Circulation Counts
Using observed mobile trip data, information from Departments of Transportation, and factors such as illumination and directionality of the frame, we determine the audience’s “opportunity-to-see” to arrive at a circulation count.

Audited Viewsheds
Using eye-tracking research, speed data, and information related to the frame, including dwell time and proximity to the audience, we determine the likelihood of seeing an ad on an OOH display.

Reach & Frequency
Using observed mobile trip data, we understand how frequently an ad will be seen on a display and by how many unique individuals.

Demographics
Using household data from Claritas, we create population profiles to deliver insights related to target demographics.
